The Chelsea 489QQMEX-66RY is a mechanical shift Power Take-Off from the Chelsea 489 Series, engineered for 8-bolt manual transmission openings including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt aperture, eliminating the adapter plate and reducing potential leak paths. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 48 HP at 1,000 RPM via a 1-1/4" round keyed output shaft. Wire/cable mechanical shift operation and tapered roller bearings provide durable load-bearing capability across vocational applications including dump trucks, utility trucks, and snow and ice removal equipment. Sold by Pro Gear and Transmission.
